My car is running rich and like a dog.

Before: Fuel pressure at 38 at idle with vac attached and 45 detached. Under WOT it would go to 45. Car ran *****.

After: Fuel pressure at 45 at idle and does not change now even with vac dettached.

A little more info....turbo d16z6 on RC 370's and Walbro 255, tuned on Uberdata. The guage and FPR are B&M. I first thought it was just the gauge, but i pinched the fuel line and the gauge reacted. So now I am left to believe its my FPR...but still wonderin why my fuel pressure does not change with vac on or off. Also, my B&M is turned out all the way now and it did not lower the fuel pressure....but still raises it if I turn it it?

Help guys?

But first, make sure you don't have a blockage or pinched fuel return line.

 

anyone else?

 

Return line screwed up or bad fpr.. I had the same problem with my crx and it was the return line crushed above the gas tank..
